Introduction
WARNING: Unless specifically required, DO
NOT have engine running when servicing or
making adjustments to tractor. Place H-bar
handle in the neutral position, disengage deck
clutch, lock neutral lock lever, and remove
ignition switch key. Repairs or maintenance
requiring engine power should be performed by
trained personnel only. To prevent carbon
monoxide poisoning, be sure proper ventilation is
available when engine must be operated in an
enclosed area. Read and observe safety warnings
in front of manual.
DANGER: Before working on or under the
deck, make certain engine cannot be accidentally
started. Shut engine off and remove ignition

switch key for maximum safety. Repairs or
maintenance requiring engine power should be
performed by trained personnel only.
DANGER: Exercise caution when working
under the deck as the mower blades are
extremely sharp. Wearing gloves is advisable
when working around or with the blades.
WARNING: Except when changing or checking
belt, always keep belt covers on mower for
safety as well as cleanliness.
WARNING: When possible clean under mower,
using a stick or similar instrument making sure
that no part of the body, especially arms and
hands are under mower.
Regular maintenance is the best prevention for costly
downtime or expensive, premature repair. The following
pages contain suggested maintenance information and
schedules which the operator should follow on a routine
basis.
Remain alert for unusual noises, they could be signaling
a problem. Visually inspect the machine for any abnormal
wear or damage. A good time to detect potential problems
is while performing scheduled maintenance service.
Correcting the problem as quickly as possible is the best
insurance.
WARNING: Keep your machine clean and
remove any deposits of trash and clippings,
which can cause engine fires and hydraulic
overheating as well as excessive belt wear.
Clear away heavy build-up of grease, oil and dirt,
especially in the engine and hydraulic reservoir area; minute
dust particle are abrasive to close-tolerance engine and
hydraulic assemblies.
Daily inspect mower for grass clippings and wire and
string tangles. The underside of the mower deck will collect
a build-up of grass clippings and dirt, especially when grass
is wet or has high moisture content. This build-up will
harden, restricting blade and air movement and will
probably show a poorer quality of cutting. Therefore it
should be removed routinely.
To do this it will be necessary to raise and block the deck
in the full up position and scrape the build-up from
underneath.
Some repairs require the assistance of a trained service
mechanic and should not be attempted by unskilled
personnel. Consult your Hustler service center when
assistance is needed.
Description of deck operation
The blades are indirectly driven by the engine through a
V-belt drive system. The V-belt drives a pulley located on
top of spindle housing assemblies. The pulleys drive 1"
spindle shafts which in turn drive the blade saddles. A blade
is affixed to each blade saddle by a 1/2" bolt.
